Abstract (en)
[origin: US6484640B1] The invention relates to a method of producing a screening smoke which is one-way transparent in the infrared spectrum (780 nm-14.0 mum) and opaque in the visible spectrum. According to the invention a known pyrotechnic screening smoke which is highly absorbent in the visible spectrum (380 nm-780 nm) is generated in the form of an aerosol, pyrotechnic scattered particles between 10 and 100 mum in size are simultaneously produced in said aerosol, and the resulting two-component smoke is irradiated by an infrared radiation source (spectrum: 780 nm-14.0 mum) from the smoke producer side.
